lLLUMlNATlNG-TILE.

SPECIFICATION forming part of Letters latent No. 436,083, datedSeptember 9, 1890. Application filed March 9, 1889. Serial No. 302,593-(No 11106181 To all whom it may concern:

Be it known that I, JACOB JACOBS, of New York, in the county of NewYork, and in the State of New York, have invented certain new and usefulImprovements in Illuminating-Tiles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accornpanying drawings, in which* Figure 1 is aperspective View of the exterior and interior lenses separated from eachother. Fig. 2 is a like view of the same combined and in position withina supportingframe, and Fig. 3 is a section upon line a: 00 of Fig. 2.

Letters of like name and kind refer to like parts in each of thefigures. 7

My present invention is an improvement upon an illuminating-tile forwhich Letters Patent No. 364,113 were issued to me upon the 31st day ofMay, 1887, and is designed to remedy certain difficulties that have beenencountered in the manufacture of said tile; to which end my saidinvention consists, principally, as an improvement in illuminatingtiles, in a lens having two recesses in it, in combination with aseparately-formed lens fitted to and secured within the upper of saidrecesses, substantially as and for the purpose hereinafter specified.

It consists, further, as an improvement in illuminating-tiles in whichthe light-openings are covered by lenses that are each provided with tworecesses and combined with a separately-formed lens having a differentcolor, said colored lens being contained within the upper of saidrecesses, substantially as and for the purpose hereinafter shown.

In the carrying of my invention into practice I usually employ a metaltile A, in which the light openings a and a are square and arranged inparallel lines, as shown, and each of such openings is provided aroundits lower edge with an inwardly-proj ecting supportingledge a.

lNithin each light-opening a is placed a correspondingly-shaped glasslens B, which substantially fills the space laterally, and is held inplace therein by a cement joint 0, that is made in the usual way betweenthe inner walls of said opening and the outer sides of said lens. Withinthe upper side of the lens B is formed a recess 1), which preferably isround and extends downward about one-half the thickness of said lens,and within such recess is placed a second lens D, that correspondsthereto in size and shape, and is secured in place by a cement joint E,which is formed between its periphery and the-wall of said recess.Either or both of the lenses B and D may be colored, and they arepreferably formed from different-colored glasses, while the cement usedfor the joint E may also be colored, if desired, by which means theappearance of the tile both from without as well as from within ismaterially enhanced and beautiful effects rendered easy of production.When one of said lenses is made from uncolored glass, thelight-transmitting capacity of the tile is but slightly diminished. Thelower side of the lens B is preferably re cessed, and the top of suchrecess 1) is preferably made convex and ornamental, as shown in Fig. 5.As thus constructed it is found that the light-transmitting capacity ofthe combined lenses is but slightly less than in case of a single solidlens, and fully equal to the lenses shown in my hereinbefore-namedpatent, in which the outer lens had an open center, while in theconstruction of said outer lens the recessed form is much, more easilymade and costs less than does the open center form.

Having thus described my invention, what I claim is- 1. As animprovement in illuminating-tiles, a lens which has two recessesprovided in it, in combination with a-separately-formed lens fitted toand secured within the upper one of said recesses, substantially as andfor the pur pose specified.

2. As an improvement inilluminating-tiles,

a lens which has two centrally-disposed recesses arranged one above theother, in combination with a separately-formed lens placed within theupper recess, entirely filling the same, and having its upper face flushwith the upper face of the inclosing-lens, substantially as and for thepurpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this2d day of March, 1889.
